기술집약적인 경제성장의 중요성이 강조되고 있는 가운데 이공계 진학과 과학기술직종선택의 감소는 성장잠재력에 가장 근본적인 위협이 된다. 이를 유지하려는 여러 가지 정책이 교육학적이나 사회학적 근거에서 제시되고 있으나 이를 분석하는 이론적 경험적 틀이 상대적으로 부족한 상태이다. 직업선택모델은 사회학적인 접근법이 활발하게 진행되었으나, 경제적 동인에 대극 분석이 부족하다. 본 논문에서는 2000년 미국 센서스 데이터에 나타난 가장 국제화된 미국의 과학기술직 사례를 통해 인적자본 모델을 기준으로 하여 기술직에 대한 기존의 연구와 비교한다. 이민의 직업선택모델의 관점에서 원주민의 경우와 비교하며, 동시에 타 직업군과 비교한다. 직업선택에서 미래소득에 대한 예측이 대체로 정확하나 실제의 선택이 다르다는 기존 논문들의 주장은 성간 차이의 문제를 제외하고는 현격하지 않다. 민족적 차이의 효과도 인적자본효과에 비해서는 크지 않다. 과학기술직은 고급 화이트칼라 직종에 비해 결혼과 교육 언어 경험면에서 저급한 직종의 특성을 보인다. 여성의 과학기술직 기피는 남성프리미엄이 높아서는 아니지만 합리적인 차별 때문으로 볼 수 있다.

Predominant explanations of the persistence of sex segregation ill occupations link job choices to profoundly gendered responses to childbearing and other family demands, arguing that women are more likely to seek jobs which are in some sense compatible with motherhood, either because they are family friendly (flexible, low intensity work) or because they are easy to exit and re-enter. In this paper, I examine the effect of occupational sex segregation on job exits into the labor market among women, with a special attention to the role of childbearing and child rearing. I use data from detailed employment histories gathered from the National Longitudinal Survey of Youth (NLSY) in continuous time event history models. My results indicate that women in female dominated jobs are less likely to exit their jobs than women in other types of occupations. Further this relationship is not shaped by motherhood. While mothers or pregnant women are more likely to leave work, mothers in female-dominated occupations are slightly less likely to leave employment than mothers in other occupations. These results are not consistent with the ideas that women's choice of female-dominated occupations expresses a gendered identity and women strategically seek jobs which accommodate maternal roles. Taken together, my findings do not provide support to the idea that women choose female-dominated occupations because they are easier to integrate with motherhood (except for the pregnancy period).

This study examines the job changes and the coincidence of job and major In the case of the youth, science and engineering graduates in Korea. The pattern of job changes and the coincidence of job and major get observed in the Unemployment Insurance Database and the Graduate List. This data enables us tracing all job changes in the labor market, and analysing the coincidence of job and major. The average rate of coincidence is not so high, the rate at first job is roughly one third. The youth with coincidence of job and major have earned less income than the youth without coincidence of job and major. But this result is impressive in the lower wage earners, any differences in regard to coincidence is not found in the upper wage earners. The probability of the coincidence of job and major is higher in case of the high wage and the high study attainments. The results suggests that the problem of the science and engineering graduates should be concentrated only on the lower manpower in the scientist and engineer jobs. Korean government have to lessen the number of entry into the science and engineering college and enlarge the number of entry into the science and engineering graduate school. Korean government have to prepare the system that aids establishment where the employee with coincidence of job and major earns more income.

We find that there is the height premium in the Korean labor market. The wage increases by 1.5% with a centimeter increase of height among male workers of ages 30-49. This estimate is barely affected by family backgrounds such as a worker's father's education or occupation. It is rejected that a worker's height is a proxy variable for his health, which increases his wage. The height premium is unrelated with obesity. It is not also supported that a worker's height affects his wage through his occupational choice. We partly confirm that a worker's height affects his wage through his educational choice. The estimated height premium of 30's in Korea is comparable to that of age 33 in Great Britain.

This study shows a theoretical model, based on transaction cost theory, for the choice of alternative work arrangement, Suppose that standard labor contract (permanent and full-time) is a typical labor contract of within-organization transaction and alternative labor contracts of variety are in the spectrum between market and within-organization transaction, the type and size of the market transaction cost for a specific labor would determine the appropriate labor contract. Firm-specificity and level of skill, scope and uncertainty of tasks, and duration of contract are the major determinants of transaction cost which, in turn, determines the type of labor contract. This theoretical model implies that there will be occupational segregation between standard and alternative work arrangements and that the legal regulations for protecting employment and wage of non-standard workers might not be so effective as expected.

In modern society, as technology develops and industry diversifies, students can choose from a variety of career paths. Since science, technology, engineering, and mathematics require a longer education and experience than other fields, it is important to design science education policies based on the competencies required for science, technology, engineering, and mathematics (STEM) occupations. This study explores the definition of science and technology manpower and STEM occupations and identifies core competencies of STEM occupations using standard job information operated and maintained by the US Department of Labor ($O^*NET$). We specially analyzed ratings of the importance of skills (35 ratings), knowledge (33 ratings), and work activities (41 ratings) conducting descriptive analysis and principal component analysis (PCA). As a result, core competencies of STEM occupations consist of STEM problem-solving competency, Management competency, Technical competency, Social service competency, Teaching competency, Design competency, Bio-chemistry competency, and Public service competency, which accounts for 70% of the total variance. This study can be a reference for setting the curriculum and educational goals in secondary and college education by showing the diversity of science and technology occupations and the competencies required for STEM occupations.

The authors conducted a cross-setional study to evaluate the differences of screening test results between clerks and laborers in an occupational health center in Taegu, 1992. A total of 10, 207 workers was included in the study. Of these, male were 6,597 and female 3,610. Constitutional variables included were items of health examination and some confounding variables(sex, age, body weight and work duration). All analyses were conducted separately for each sex through the use of multiple logistic regression analysis on occupation, controlling for age, work duration, and body weight. Laborers showed abnormal hearing test more often than clerks in both sexes. The blood pressure that showed statistical significance in univariate analysis in both sexes lost its significance after controlling covariates. Liver function and urine protein had statistically significant differences between two occupational groups in males and visual correction did in females. The results suggest that there are differences clerks and laborers in some of screening tests and analytic studies are needed to identify the causes of the differences.

This study examines difference in age at marriage between spouses and more importantly, investigates into the economic and social factors affecting the ratio or probability of wife-older marriages. Empirical analysis is carried out by applying both logit model and multinomial logit model to an independently pooled cross-section over 2004-2007. The data was collected mainly from the micro data service system of the Statistics Korea. Empirical results indicate that a wife-older marriage was more likely as a wife was more educated and was a larger income earner than a husband. On the other hand, a wife's educational and income level themselves had few systematic relationships with the probability of a wife-older marriage. The probability of a wife-older marriage tended to decrease(increase) when a husband's(a wife's) marriage was the second' The study calculates the average marginal effect of difference in the income level between spouses on the probability of a wife-older marriage, which is -0.007. That is, the probability of a wife-older marriage increases by 0.7% as a husband's income level is 1 million Korean Won less than a wife's. This results presents empirical evidence against widely distributed misconception on wife-older marriage in the mass media.

This study was to analyze the media-contacting motivation and the optional seeking behavior for the informations, namely, what kinds of media the information users contact and what types of informations they select for the purpose of meeting their needs of the informations. For this purpose, the questionaires answered by 277 of the employees including the professors, reseatchers, teachers, officials and collegians were analyzed by properties. The Result of this analysis is that the new hints or ideas by the professors and the researchers appeared in the highest at the academic meetings or the reseatching activities and those at the other employees appeared at the internet sites. It was shown that there is a very close correlation between the information-seeking behaviors and the user properties as the types of their seeking informations and their information-seeking morivations are considerably different from each other.
